Milestone LD-116UDRMP RS232 to 16 Port RS485 Distributor : LD-116UDRMP
Milestone LD-116UDRMP RS232 to 16 Port RS485 Distributor : LD-116UDRMP
The Milestone LD-116UDRMP is a high-density RS232 to RS485 serial data distributor engineered for industrial and AV connectivity applications. It accepts a single RS232 input and distributes it to sixteen buffered, optically isolated RS485 outputs simultaneously, allowing one host computer or PLC to reach many remote devices in both directions. Every output line carries its own surge protection, keeping communication stable in electrically noisy plant, factory and control-room environments. The rack-mount panel format keeps large multi-port installations organised and easy to maintain inside standard equipment racks.
Key Features
Key Features
• 1-to-16 RS232 to RS422/RS485 Distribution Hub: Converts a single master RS232 input channel into sixteen independent, optically isolated RS422 or RS485 output channels for large-scale industrial data distribution networks.
• 19-Inch Rack-Mount Chassis (RMP): Housed in a standardized rack-mountable (RMP) industrial metal enclosure designed for standard 19-inch server and equipment racks, providing clean integration in central control rooms and SCADA hubs.
• Selectable 2-Wire & 4-Wire Operating Modes: Supports both 2-wire half-duplex (RS485) and 4-wire full-duplex (RS422/RS485) communication modes across all 16 output channels via onboard DIP switches or jumpers.
• Optoelectronic Isolation & Transient Suppression: Integrates high-voltage optical isolation and surge protection across all channels to safeguard host controllers and connected field hardware against ground loops, high electrical noise, and power spikes.
• Automatic Data Direction Control: Features automatic baud-rate detection and hardware flow direction management, eliminating the need for software-driven RTS/CTS handshaking lines.
• Comprehensive Front-Panel Diagnostic LED Array: Equipped with front-panel LED indicators for Power, Master Transmit (TX), and individual Output Receive (RX1–RX16) lines for fast real-time status and data traffic monitoring.
Applications
• Distributing commands from one PLC or PC to multiple automation devices
• Connecting many RS485 terminals to a single host in attendance and access control systems
• Broadcasting data to multiple barcode readers and remote terminals
• Fanning out control signals in SCADA and building management systems
• Expanding serial I/O for security and command-and-control installations
• Linking one serial master to many devices in large industrial networking setups
Summary
The Milestone LD-116UDRMP is a dependable, isolated RS232 to RS485 distributor that lets a single host drive up to sixteen RS485 devices simultaneously. With buffered outputs, surge protection and clear LED diagnostics, it is an ideal backbone for integrators and industries that need stable, high-capacity multi-drop serial communication.
